Black Powder Coated Steel Welded Commercial Extended Top Fence

Steel Extended Top Fence is not only a protective fence panel but also a decorative fence. It is formed by inserting piles into two horizontal guide rails and has a pile structure. The product remains visually appealing while being sturdy enough to keep you and your property safe. It can be suitable for residential areas and commercial areas, and in places that require safety protection such as factories, hospitals, schools, courtyards, and gardens.

Our steel extended top fence panel is made of galvanized steel and the frame is reinforced. The quality of this picket fence is stable, sturdy, and durable. When treated with a multi-layer protective powder coating process, it has higher rust and corrosion resistance. It increases the service life of the product and reduces maintenance costs.

To support your fast-track project delivery and bulk stocking needs, we maintain ready inventory of our most popular standard specification: 70” in height and 94” in width per panel. Every full fence set comes complete with matching high-quality brackets and pre-treated fence posts, and we also offer compatible steel extended top gates for one-stop full-system procurement, helping you eliminate extra coordination costs of working with multiple suppliers. With a prefabricated modular design, our products are fast and straightforward to install on site, helping you shorten construction periods and reduce labor costs.

As a professional Steel Fence Manufacturer with years of experience serving B-end partners, we support full customization of special sizes, styles, coating colors and structural details to align with your project’s unique design specifications, local building regulations and unique on-site requirements.

Steel Extended Top Fence Advantages 

• 360° fully welded: The horizontal rails, with evenly punched holes, and upright pailings are fully welded in a 360° manner, ensuring strong welding points and minimal split welds even after extended use.
• Keep uninvited guests and intruders out: The spear top design acts as a deterrent for any unauthorized entry. Additionally, the narrow spacing between horizontal rails prevents the creation of foot holds for climbing over.
• Choose from a variety of styles: We offer different aesthetic options for our rod top steel fence panel, including 2-rail, 3-rail, and 4-rail steel fences, catering to your specific preferences.
• Robust corrosion-resistant surface treatment: Our rod top steel fence panel steel tubes undergo full hot-dipped galvanization, with a G90 or G60 galvanized coating applied both inside and outside.

Extended Top Fence Production Process

Material

All incoming pre-galvanized steel pipes are inspected for outer diameter and wall thickness before production. We control outer diameter tolerance within ±0.2mm, to ensure all parameters fully comply with fence drawing requirements and guarantee quality from the source.

Cutting

Auto-CNC pipe cutting machine is adopted for blanking. Profiles are cut per design requirements to obtain the target length, with cutting length tolerance controlled within ±1mm, ensuring burr-free and non-deforming cut ends.

Punching

Punching is processed on cut pipes with customized positioning jigs. We control aperture tolerance within ±0.1mm and hole position deviation within 0.5mm to meet the accuracy requirements of subsequent assembly.

Welding

We use automated gas shielded welding technology to assemble pre-galvanized steel pipes into fence panel frames. Weld leg size is controlled between 3-5mm, with no weak welding, missing welding or slag inclusion; weld tensile strength reaches no less than 300MPa to ensure solid structural strength of the frame.

Surface Pretreatment

After sandblasting, phosphating treatment is performed to form a uniform phosphating film on the workpiece surface, with film thickness controlled at 1-3μm. The phosphating film itself has certain anti-corrosion capability, and can provide excellent adhesion for paint, powder coating, and other organic coatings, effectively extending the service life of the final coating.

Cleaning

A pure water rinse follows to eliminate residual impurities, oils, and contaminants, resulting in an exceptionally smooth and clean surface ready for the next coating stage.

Powder Coating

Electrostatically spray epoxy-polyester hybrid powder on the pretreated workpiece surface, then transfer it to a curing oven and cure at 180-200℃ for 15-20 minutes. This process endows the finished product with outstanding rust resistance and corrosion resistance, and delivers a uniform, aesthetic coating.

Quality Control

We carry out full inspection for each finished product, testing pipe wall thickness, structural connection strength, and powder coating thickness. The coating thickness is controlled within 60-120μm to ensure all products meet delivery standards, and unqualified products are blocked before leaving the factory.

Packaging

We use a combined packaging solution of stretch film, reinforced square cardboard corner protection and strapping tape to secure the product.

Powder Coated Extended Top Fence Application

• Residential area: Suitable for residential, such as gardens, pools, and other fields.

Galvanized Steel Extended Top Fence FAQ

Q: What’s the difference between steel extended top fence and flat top fence?

A: Steel extended top fences have vertical bars that extend upward with extended ends to create an anti-climb barrier, enhancing security against scaling. In contrast, flat top fences feature a smooth, horizontal rail at the top without extensions, offering a cleaner aesthetic but less deterrence for climbing.

Q: How does the pre-welded design of the extended top fence simplify on-site assembly?

A: The pre-welded panels arrive ready-to-install, eliminating the need for complex welding or custom fabrication at the job site. This modular approach allows for quick alignment and securing with basic tools, minimizing errors and enabling faster completion even for crews with varying experience levels.

Q: Do you offer customization for size, color and other specs to fit specific project or inventory needs?

A: Yes, we support full flexible customization. Beyond our standard sizes and popular black finish, we can adjust panel dimensions, rail/picket gauges, and provide custom colors to match your project requirements. We also offer private labeling services for wholesale distributors to support your independent brand.

Q: What is the minimum order quantity for a trial order?

A: Typically, we require a full 1*20′ container to ensure safe transport of the products. However, we are flexible and can accommodate smaller orders based on your requirements.

Q: How about the delivery time of products?

A: For standard specifications, we have standard products in stock, which means we have them in stock. If you need such a product, it can be shipped to you as soon as possible.
